Sphinx

The documentation is uses Sphinx, which provides the structure and hierarchy of the documentation. It is the engine which renders the source text into HTML, PDF and ePub formats. You can install and use Sphinx to build the documentation to see what it will look like before pushing a change, but it isn't required.

Read The Docs

The CloudStack documentation is built using the ReadTheDocs service. ReadTheDocs takes the source text and runs it through the Sphinx engine to produce the documentation and also hosts the output. Access is not strictly required in order to write/update the source documentation. Only to build the documentation for a new version.

If you would like access, please contact the dev list.

reStructuredText

This is the authoring language that is used while write individual topics. reStructured text (RST) is the markup language that allows us to denote, headings, sections, bullets, bold text, italics etc.
